Rails 3.2.13
我基本上是尝试使用此截屏视频进行部署：http://railscasts.com/episodes/335-deploying-to-a-vps
我有一个可以在开发中使用的应用程序，但是当使用Capistrano推送到生产时，我的一个控制器操作几乎全部产生404页。
当我运行'rake routes'时，我注意到输出中缺少此控制器的操作：
的routes.rb
Wagmantechnology::Application.routes.draw do

您会看到没有列出任何资产路线。为什么？奇怪的是，索引动作/资产在生产中起作用，但没有别的。所有链接都在开发中。我在这里做错了什么？
答案 0 :(得分：2)
原因应该是名称与资产管道冲突。
路由中的“资产”一词过于敏感，与Rails静态资产相同。您可以验证localhost:3000/assets/rails.png是否可以在开发环境中运行，但不能生成。所有“资产”路线都已在生产模式中更改。
我的建议是将您的路由名称空间从“assets”重命名为其他名称。但这可能涉及很多工作。我还不知道其他更简单的方法。
<强>更新 感谢@ sevenseacat的评论。他指出了一种更简单的方法 - 改变资产路线
config.assets.prefix = "/some_other_path"
